Global Ancestry K38 — Modern-era admixture calculator
What this calculator analyzes
This tool computes proportional ancestry components using a 38-cluster admixture model applied to modern global populations. It compares your genotype to curated reference groups to estimate the proportion of heritage derived from continental, regional and subregional sources.
Who it's designed for
- Genetic genealogists, adoptees, and curious consumers seeking detailed ancestry breakdowns
- Population geneticists and students who want a compact, interpretable modern-era model
- Anyone interested in broad migration signals rather than fine-scale community-specific signatures
Insights you can gain
- Percentage breakdown of ancestry across Europe, Asia, Africa, the Americas, and Oceania
- Detection of multi-regional admixture (e.g., Eurasian + African + Native American contributions)
- Relative affinities to fine-grained references such as Scandinavian, West African, Mongol, Polynesian, and Mesoamerican clusters
- Context for recent migrations and mixture events reflected in your genome
Historical and genetic context
K-models partition genetic variation into interpretable components that reflect shared ancestry and historical migrations. This modern-era K38 emphasizes present-day population structure—useful for reconstructing recent admixture and continental-level ancestry—while intentionally excluding separate Jewish clusters to avoid overfitting to those community-specific signatures.
Why this calculator is valuable
- Broad, globally representative reference set (35 major groups) for robust, comparative results
- Balanced resolution: detailed enough to be informative, simple enough to avoid misleading micro-assignations
- Clear presentation of admixture proportions to inform genealogical hypotheses and research leads

Cómo interpretar el análisis de mezcla genética
Descubre cómo funcionan las calculadoras de mezcla genética y cómo interpretar los resultados
¿Qué es el análisis de mezcla genética?
El análisis de mezcla genética estima la similitud genética comparando tu ADN con poblaciones de referencia de distintas partes del mundo. Los componentes del modelo representan esas referencias y dependen de los datos y supuestos utilizados.
Esta calculadora utiliza 38 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 38 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Los resultados muestran tu similitud genética con estas poblaciones
- La diversidad del panel de referencia influye en las estimaciones
Cómo interpretar tus resultados
Los resultados muestran porcentajes de similitud genética con estas poblaciones de referencia. Ten presentes estos puntos:
- Los resultados reflejan similitud genética, no ascendencia directa demostrada
- Modern se utilizan como referencias
- Los porcentajes indican contribuciones relativas en el modelo
- Los resultados son estimaciones basadas en los datos de referencia disponibles
